the light-shielding member overlaps the portion in the plan view.
2. The display device of claim 1 , wherein the light-shielding member is a third adhesive layer made of resin.
3. The display device of claim 1 , wherein a part of the second adhesive layer is located between the third adhesive layer and the second surface.
4. The display device of claim 1 , wherein the liquid crystal display panel comprises a first substrate and a second substrate, and
the light-shielding member is in contact with a first side surface of the first substrate and a second side surface of the second substrate.
5. The display device of claim 4 , wherein the second substrate is located between the first substrate and the frame-shaped structure,
the liquid crystal display panel includes a first polarizing plate located between the frame-shaped structure and the second substrate, and
the light-shielding member is in contact with the first polarizing plate.
6. The display device of claim 4 , wherein the second substrate is located between the first substrate and the frame-shaped structure,
the liquid crystal display panel includes a second polarizing plate, the first substrate being located between the second polarizing plate and the second substrate, and
the light-shielding member is not in contact with the second polarizing plate.
7. The display device of claim 1 , further comprising a first optical sheet between the liquid crystal display panel and the frame-shaped structure,
wherein the light-shielding member is in contact with the first optical sheet.
8. The display device of claim 7 , further comprising a second optical sheet between the liquid crystal display panel and the reflective sheet,
wherein the light-shielding member is not in contact with the second optical sheet.
9. The display device of claim 8 , further comprising a lightguide located on the reflective sheet,
wherein the frame-shaped structure surrounds the lightguide, and
the second optical sheet is located on the lightguide.
10. The display device of claim 9 , wherein the second optical sheet is not located on the second surface.
11. The display device of claim 1 , wherein the first adhesive layer is a frame-like shape on the first surface.
12. The display device of claim 1 , wherein the frame-shaped structure is a rectangular shape with four sides, and
the first adhesive layer is located on the four sides successionally.
13. The display device of claim 1 , wherein the frame-shaped structure is a rectangular shape with a first side, a second side, a third side, and a fourth side, and
the second adhesive layer is located on the first to third sides successionally, and is not located on the fourth side.
14. The display device of claim 13 , wherein a printed circuit board is located on the fourth side, and
the frame-shaped structure is located between the printed circuit board and the reflective sheet.
15. The display device of claim 14 , wherein the backlight device includes light sources, and
the printed circuit board is electrically connected to the light sources.
16. The display device of claim 1 , wherein a printed circuit board is located on the first region, and
